IMPROVEMENT IN GRAIN-CAR DOORS.

Specification forming part of Letters Patent N0. 201,963, dated April 2,1878; application filed March 14, 1878.

To all whom it may concern:

Be it known that I, DENNIS F. VAN LIEW, of Aurora, Kane county, State ofIllinois, have invented a new and useful Improvement in Grain-Doors forFreight-Oars, of which the following is a full description, referencebeing had to the accompanying drawing, in which- Figure 1 is anelevation, showing the inside of one sideof a car with my door closed.Fig. 2 is a like view with the door open. Fig. 3 is a vertical sectionat line a: 00 of Fig. 2. Fig. 4 is an enlarged detail.

My invention is primarily designed to be used in cars used in thecarriage of grain. Its object is to provide a simple, cheap, andefficient hinged door for such cars, which can be easily opened andclosed; and it consists in a socket secured to one of the upper cornersof the door, which socket receives a pin having a head on the outer end,provided with a hole, through which passes a rod, which is permanentlysecured at both ends to the car. The headed pin slides up and down onthe rod, and the door is pivoted on said pin, as more fully hereinafterdescribed.

In the drawings, A represents the side of a car; B, an opening ordoorway, which may be closed in the usual manner by a sliding door onthe outside 0, an inner grain-door; F, an ironrod about an inch and aneighth in diameter, secured at its ends to the top and bottom of the carinside of one of the door posts, and far enough therefrom to permit thedoor 0 to pass between the rod and side of the car. a. is a metal socketinserted in one corner of the door 0. The socket has a flange, b, and issecured to O by screws, which pass through this flange. c is a pin,which is inserted in the socket a. This pin has a head on one end,provided with a hole, e, large enough to receive the rod F. f is a blockof hard wood, secured to the car, so that the end of the door 0 can reston it when open. Its ends are inclined, as shown. 9 is a stop, withwhich the edge of C may come in contact when opened. it is a metal shoe,which receives and holds the end t of the door 0 when closed, andis soconstructed that this end of the door cannot be lifted up when closed. Mis a lock or fastening, to hold the door in place when closed.

A flush lift of the usual construction is to be secured to the door 0 onthe outside, near its hinged end. 7

The door 0 should not extend much, if any, at its hinged end (especiallythe lower part thereof) beyond the rod F; but to provide a suitableplace for the stud a and its flange, the door has an extension, 70, atthe upper in ner corner.

A convenient way to secure the rod F in place is to bolt its upper endto the car, the lower end entering a metal socket secured in the bottomof the car.

In use, the door, when closed, occupies the position shown in Fig. 1,and is held there by suitable fastenings, above referred to. It can beeasily opened by releasing the fastening M, and then lifting the hingedend of the door, when the head 01 of the pin 0 will slide upward on therod F, the door 0 at the same time turning on the pivot 0, so that thehead 01 will not bind on the rod F. When fully open the door 0 willoccupy the position shown in Fig. 2.

What I claim as new, and desire to secure by Letters Patent, is asfollows:

In a railroad freight-car, the door 0 and rod F, in combination with theheaded pin or pivot 0, provided with a hole, 6, and the socket a,substantially as and for the purposes set forth.
